After applying the shown Puppet manifest, which two entries in the /etc/hosts file will remain unchanged?

To determine which entries in the /etc/hosts file will remain unchanged after applying the Puppet manifest, it's essential to consider how Puppet manages resources, particularly with regard to file management and potential changes it may implement based on the defined manifest.

The first entry refers to "10.20.1.62 sles11a zypper." Given that this entry is specified in the context of the question and suggests a specific setup or role, it is likely that this entry is not likely to be altered by Puppet unless explicitly targeted or modified in the manifest. If the manifest does not reference this entry specifically, then it will remain unchanged.

The other entries involve different IP addresses and hostnames. If the Puppet manifest explicitly manages the hosts file and includes definitions for other specific hostnames or IP addresses, it could result in changes to those entries based on the state described in the manifest. Therefore, without a clear reference to the first entry in the manifest, it stands to reason that it would remain intact, while others may vary based on the state Puppet applies.

This understanding highlights Puppet’s declarative nature, where it ensures the defined configuration is applied, and anything not specified may remain as-is, maintaining existing entries that are not directly modified by the manifest.
